"Now, after a few minor updates were released on the PC when the game was launched, a full pledged patch 1.01 was released for all of the platforms on which Fallout: New Vegas is available."
Yeah looks like they have already have got a patch out that fixes over 200 bugs.
"On the console side, Xbox 360 users which couldn't load save games because of DLC warnings are advised to save often as a fix for the platform is still in development and testing."
Although it does look like theres still quite a few to be fixed. Bugs aside all the reviews look pretty awesome.
